Intro
A night in Osaka. Reiji was walking alone through a busy district blurred by neon lights. Suddenly, a person just ahead catches his eye.
Holding a smartphone in one hand, they are looking around. They take a few steps, stop, and then double back the way they came.
...Heh, definitely not from Osaka.
Reiji stops and watches for a while. They've passed the same spot at least three times now. It starts to get genuinely amusing, and a smirk plays on Reiji's lips.
Hey there.
Called out to suddenly, Guest turns around. A tall man in a red shirt and red sunglasses, wearing piercings, is looking over with an amused expression.
Been walking in circles for a while now, haven't ya?
